How to Choose Between Automatic and Semi-Automatic Water-Activated Tape (WAT) Carton Sealers — and Why Choose JL3

How to Choose Between Automatic and Semi-Automatic Water-Activated Tape (WAT) Carton Sealers — and Why Choose JL3

In any carton packaging operation, consistency, speed, and cost-efficiency are critical.

Choosing the right sealing equipment is a key step toward achieving these goals.

But how do you know whether an automatic or semi-automatic sealer is right for your needs?

Understand Your Needs

- Semi-Automatic WAT Carton Sealers

These machines require manual positioning of cartons before sealing. They’re ideal for production lines where carton sizes remain consistent.

Models like our KN-1717U offer manual height and width adjustments—an efficient and budget-friendly solution for uniform packaging tasks.

- Fully Automatic WAT Carton Sealers

Machines like the KN-1721R require minimal operator input and automatically adjust to various carton sizes.

They’re perfect for high-volume packaging with mixed-size boxes, enabling faster throughput and stable productivity.

Why Use a Carton Sealer?

Boost Efficiency

WAT carton sealers significantly reduce sealing time—especially vital in high-output operations. Automation helps eliminate bottlenecks and keeps your workflow smooth.

Reduce Labor Costs

Minimize manual sealing tasks so staff can focus on higher-value activities. Fully automatic systems can reduce overall manpower needs on the line.

Consistent Seal Quality

Both semi- and fully automatic machines ensure uniform water application and tape sealing, improving packaging quality.

Minimize Tape Waste

WAT sealers are programmed to dispense just the right amount of tape. One strip is enough to seal a box securely—cutting material waste and saving costs.

Which One Should You Choose?

Choose a fully automatic sealer if you handle varied carton sizes and need fast, efficient processing.

 Choose a semi-automatic sealer if you're working with consistent carton sizes and want a more economical option.
